Spool-silk is packed. for the retail trade in pasteboard boxes, eachcomprising a body or tray and a cover. In the preferredform of the boxeswhich are employed for the purpose the cover has flanges which extenddown around and inclose the side and end fianges of the body or tray,concealing the latter. It has been proposed to apply to the end flangesof the body or tray imprints or markings designating the size and colorof the contents thereof in order to identify the said color and size andto form in the opposite ends of the cover openings or peep-holes throughwhich the saidmarkings or imprints will be visible when the cover is inplace upon the body or tray, thereby enabling the marking of the coveritself to be dispensed with, if de sired, and obviating all liability tothe placing of wrongly-marked covers upon given box bodies or' traysafter removal of the covers from the latter in making display of thecontents in effecting a sale or for other purposes.

The object of my invention is to facilitate the manufacture ofbox-covers having the said openings or peep-holes in the flanges of thesame and also having so-called thumbholes" in the opposite side flangesof a box-` cover, at the lower edges thereof, to facilitate theoperation of separating a box belly or tray and its cover from eachother by permitting the box body or tray to be grasped and held atopposite sides thereof by the finger and thumb of one hand placed Withinthe said open thumb-holes, while the boxcover is grasped by the otherhand and lifted off thereby.

The invention consists in a novel machine by means of which the openingsor peepholesand thumb-holes are all punched at one operation in therespective anges of a boxJ cover.

The invention is illustrated in the accompanying drawings, which latterrepresent a rbox provided with a cc ver having the openings or peepholesand thumb-holes aforesaid formed in its flanges and also represent a,machine containing org embodiment of the invention.

In the drawings, Fig ure 1 is a front elevation ofthe said mach ne. Fig.2 is an end elevation thereof. Fig. 3 is a plan thereof. Fig. Il is aview in section in the plane indicated by the dotted line 4 4, in Fig.3. Fig. 5 shows in side eleva ion one of the movable thumb-hole dies andits carrying-plunger.

Fig. 6 is a view there )f looking fromthe leftl hand side in Fig. 5.Fig. 7 shows in side elevation one of the movable peep-hole dies and itscarrying-plunger. Fig. 8 is a view thereof looking from the li ift-handside in Fig. 7.

Fig. 9 is a plan vie v,A on an enlarged scale, n

partly broken away. of one of the sets of devices for punching theopenings or peep-holes` in the end flanges of a box-cover. F ig. 10 is apartly sectional side elevation thereof. Fig. 11 is a perspective of abox such as has been mentioned hereinabove. Fig. 12 is a perspective ofthe box body or tray. Fig. 13

is a perspective of the box-cover.

Having reference to the drawings, in Figs. 11 and 12, 1 designates a boxbody or ray. The upright side iianges of the said box body or tray aredesignated. 1a 1a, and 1b 1b arethe upright endflanges thereof. The nameof the color of the intended contents of the box and the letter whichindicates the size of such contents are marked upon the outersurfaces ofthe endflanges 1b 1'?.

In Figs. I11 and 13 the box-cover is designated 2l the depending sideflanges thereof being shown at 2'l 2a and the depending end flangesthereof being shown at 2b 2b. ln the said figures the opening,peep-hole, or Window, as it sometimes is termed, that is formed in eachof the end iianges 2b Qbis desi gnated 2. At 2d is the integral bar thatis left below the said opening, peep-hole, or window to keep the loweredge of the end flange 2b intact; and thereby strengthen the same. Thethumb-hole that is formed in the free lower edge of each depending sideflange 2f of the cover 2 is shown at 2e in Figs. 11 and 13.

Referring now to themachine, at 3, Figs. l, 2, and 3, is the bed-plateof the machine, and at 31 31, Figs. 1 and 2, are legs or uprights by Ioowhich the bed-plate supported. The bedplate is formed with oppositely-located grooves 3232, Figs. 1 and 3, extending from opposite sides ofthe bedlate toward the center `thereof and within W ich are mounted thethumbfhole-punching devices, presently to be described. It is formedalso with opprosite grooves 33 33, Figs. 2 and 3, extending n om theopposite ends of-the bed-plate toward the center of the latter andwithin which are located the devices, resently to be de- I' scribed, forpunching t e openings, peepholes, or windows aforesaid. At its centerthe bed-plate is formed with an opening 5,

Fig. 3, extending vertically therethrough, for' 'the escapeof thepunchings or chips.

To the bedlate '3 are ap lied positioningr devices for t e covers Whicare to be punched, such .devices comprising in vthe present instancewith a foot portion or fiange' 61, projecting horizontally therefrom.This foot portion or flange 61 is engaged by a clamp 7, the inner l endof which rests upon the upper surface of the foot portion or flange 61,while the outer portion of the said clamp, which portion of the clamp issomewhat thicker than theinner ortion thereof, rests upon the surface ofthe yed-plate itself, asshown'best in F 1 and 2. The clam has combinedtherewith a cap-screw 8, t e stem of which passes through a slot 71 inthe clamp into a threaded hole which is tapped in the bed-plate. By

means of the said cap-screw the foot portion or flange of thecorner-guide may be coinpressed firmly between the clamp and theeed-plate, and thereby the corner-guide may b e secured in the desiredposition. 'l`he'slot- 71 extends longitudinally of the clamp, as showniii Fig. 3, t'o permit adjustment of the clamp itself toward and fromthe center. As.

'will be obvious, ywhen the .cap-screw is loo'sened the corner-guide maybe shifted toward or from the center and may be turned or swung in anydirection into any required position to accommodate a wide range ofvariations in the size of the boxes operated u pon,

after which by tightening the cap-screw the corner-guide may be securedfixddly in place.

' The thuInb-hole-punching devices are located at opposite sides of themachine. The said devices comprise at each of th c said sides a standQ,- Fig. Z3, occupying the groove 32 at such side, the said stand havingcast-iron boxes 1,0 l.()., Figs. 2 and 3, secured thereto andbeingproyided with a fixed guide-block 11, Fig. 3, intermediate the saidboxes and with an. upright end portion 12 at the inner end of the stand.The 13 slides in the said boxes 1() 1() and is flatted at 131, Fig. 5,at its under side to fit the top surface of the said guide-block 11. Bythe cont-act'of the Hatted surface 131 ofthe rod 13 with the top surfaceof the guide-block 11 the punch-carrying rod is held from turning. Thethumb-hole punch or male die 14 is attached, by means of a screw 141,Figs. 5 and 6, to the inner end of the rod 13. In the retracted positionof the rod 13 and die or punch 14 thesaid die or punch is shieldedwithin a guard-block 15, lig. 3. The fixed internal or female die 16,Figl. 3, is backed up by the upwardly-extending ort-ion 12 of the stand9. block 15 by a space of suflicient width to receive between thesame'and the said guardblock one of the side flanges of a box-cover whenthe male die or punch 14 is retracted punch-.carrying radi It isseparated rom the guardoutwardly into the opening of the guardblock 15.For the actuation of the rod 13 and its punch yor die 14 aclamping-block (shown at 1,7, Figs. 1, 2, and 3) is adjustably mountedand secured upon the outerend of the rod 13. This clamping-block isformed with a socket or seat 171,. Fig. 2, which r.- vceives theroundedy transversely-extended bar of the T-shaped head portion 181 ofan operating-lever 18. The lever 18 is pivotally mounted u .on a fixedstand 182, `which is attached to t e bed-plate 3, andi-t is actuated tomove the said rod and punch or die in one direction to effect .thepunching by IOO means of anv edge cani 19, Figs. 1 'and 2, on

the operating-shaft 20 of the machine and to move the same in theopposite direction to retract" the said rod and punch or die by means ofthe contracting spring 21, the latter engaging by one end thereof withthe lever and by the other end thereof with the opposite stand 182. y

The peep-hole-punching devices, which are located at o ipositc ends ofthe machine, comprise at eac end a stand 22, Figs. 3, 9, and 10,occupy-ing the groove 33 at such end, the

said stand 'having cast-iron boxes 23 23v secured thereto and beingprovided with a fixed guide-block 24 between the said boxes and w1 th anupright end vportion 25 at the inner end of the stand.` Thepunch-carryingV rod 26 (shown separately in Figs. 7and 8) slides in thesaid boxes 2323 and is flatted at 261, Fig. 7 at its vunder side to fitthe top surface of the said guide-block 11 to hold thel rod and the.punch carried thereby'froin turning. 'lhe rod 26 carries at its innerend thef male die orpunch 27 for forming an opening,

peep-hole, or window 1n one end flange ofa box-cover. the said die ori'uncli bein" sc-.

cured to the said end of the rod by a screw 271, shown in Figs.' 7,8, 9,and 10.

ln .the

IIO

. retracted position o the rod 26 and die or l the two end hanges or"IOv punch 2,7 the said die or punch is shieided Within a guztrd-bioclrl.(Shown best Figs. 9 and 10.) The iixcd internal or male die 29 is backedup by the upward n extending portion 2o at the inner en o' stand 22 andis separated from guard-Modi 28vby a siace of suiiicicnt width toreceive between tlhe same and the said gnard-bioch the end flange die orpunch is is retracted outwarilly into the opening of the guard-block Forthe actuation of the rod 26 and its .punch or die 27 a clamping-block30, Figs, l, 2, andi-3, adjustably mounted andv secured upon 'the outerend of 'the rod 2o. This clampingblock is formed with a socket or seatwhich receives the rounded transversi-fiy-extended bar of the ishapedhead portion 35i oi an o erating--lever 35, The lever 55 is pivota lymounted upon a iixed stand 352, that attached to the bed-plate 3, and itis operated to move rod 26 and punch or die 27 in one direction toetiect the punching' by means of a side cani 36 upon the lshaft 20, anditis operated in the opposite direction to retract the punch means of aspring 37,

Vthe said spring having one extremi there-.oi

connected with one of thc levers .35 and the other extremity thereofconnected with the other of such levers.

In the usev of the machine a box-cover is placed open side down withdiagonally opposite corners thereof Within the angles of thecorner-guides 6 and with its respective side iange's entered into therespective spaces bctween the guard-blocks l5 l5 and thev dies i6 l'andits respective end flanges entered into the respective spaces betweenthe guardblocks 28 2Sand the dies 29 29, with the :free edges of theiianges resting npon the upper surface of the bed or table 3. Thebox-cover being thus positioned, the actuation of the male dies by meansof the cams upon shaft y 2O results in the formation of the thumb-,lioles and end openings, peep-holes, or windoive, after which thebox-cover is removed 'and a fresh one placed in position to be operatedupon. The cams may be set to cause all of the four male dies to maltetheir. punching movements simultaneously, or the two thumb-hoie dies i414C may act at one time and then the peep-hole dies 27 27.

The shapes of the diiierent dios may vary in practice, according 'to theshape which is desired for the thumb-holes of the side flanges and theshape which is desired for the openings of the end flanges. The positionof the said openings in the Width ot the box-cover may vary, as desired,according to the position Which is preferred for such opening and theimprint or marking upon-the box-body. Usually the imprint or marking ofagiven end iange of a box-body is located next one side of the latter,the imprints or markingsnof of a box-co ver when the male 'such box-bodybeing disposed in diagonally opposite positions with resp-ect toeachother. in the machine shov-.fn in the drawings the punching deviceswhich zio' upon the end flanges are arranged to Form the peep-holes,openings, or Windows in this relation to each. other--that is to say, t1are arranged in diagonally opposite positions, as shol 'n best in Fig.In such iign e the ,i punching devices and the cornergnides alternate inposition with each other at the opposite ends oi the opening 5 throughthe bed or plate 5?.

To cnalile the punching devices to be adjusted to suit various sizes ofbox-covers, the stands $5 Q are made adjustable lengthwise toward andtroni each other to suit variations in the width of a box-cover, and thestands 2? 22 made adjustable toward and from each other to suitvariations in the length of a box-cover. Each yoic the four stands issecured in working position by means of a clamping bolt or bolts, asFig. 4, the stem of each of suoli boltspassing through a slot x2, thatis formed. in the bed or plate 3, and being screwed into a threaded holewhich is tapped into the under side of the stand, and a Washer or platefr being iittcd to the said stem and interposed between the headof thebolt and the under si de ci the bed or plate. Each slot is elongated inthe direction of the length of the corresponding stand, as indicatedk bydotted lines in Fig. 3, to provide for the adjustment of thecorresponding stand toward and from the center of the machine. Inaddition in order to permit stands 222 22 to be adjusted transversely tosuit dii'l'erent Widths of boxcovers the slots in connection with thesaidA stands are wider transversely than the diameters of thecorresponding bolts, as indicated in Fig. 4, and the grooves 33 33similarly are wi der than the stands 22 2.2.
